The object of the invention is to provide a roller bearing wheeljadapted to cooperate witlr an axle- Of: amine ,car :or otherwheeled vehicle in which wheeliscarrieda plurality of friction reducing means suchas a roller bearing assembly and-in which the. independentlyinovable parts of the assembly are so arranged that an ample supply-of lubricant will'at all tiniesbe'provided;

Referring specifically; tothe parts shown in the accompanying drawing 'l iudicates a hub portion .of-a wheel provided with-an axle bore 2 of relatively large diameter open at its inner end and of an enlarged and considerably exaggerated'diameter 3- at its outer end with an intermediate perforated annular shoulder or wall at preferably integral'with the hub-portion of the wheel. The awheel also is equipped with azseparately formed perforated washer. :5 which is inserted from the inner end 0f the'axle-bore. Cooperating with the wheelis a shouldered, axle v6'upon which is placed-the collar 7 within the inner end of the axle bore, this collar abutting a shoulder 8 on the .axle, and there is .a'flanged collar 9 pinned to the outer end of the{ axle with a flanged portion 10 thereon extending into the enlarged outer. portion of the axle bore at 3.

It is obvious that centrifugal force will throw any lubricant of a fluid or semi-fluid nature supplied to the Wheel towards the outer zone of any space in which such lubricant is confined, and it is this tendency which has caused untold trouble in the operation of cars equipped with wheels which rotate in contact with fixed parts of the car structure or means carried on the axle upon which the wheels are threaded. For the purpose of providing ample lubricant, a lubricating chamber is provided which is closed at its ingress port by the plug 16 or any suitable device and such lubricant is fed to the interior of the wheel through the Mmrrcaa s'rnuc'runn.

passages 17 and through coincident passages n the sleeve 18 in which the roller bearings l9 rotate around the axle 6.

{llll8 rnine cars more at relatively slow speed, 'the. speedis sui'iicientto throw the lubricant when of a semi-fluid nature to the wheelhub atits ends. There will also be sufficient-lubricant provided between the coll ar Tend the perforated washer 5 at the inner end ;of the wheel and between the inner facej of-theflange 10 and theintegral annuzlar shoulder 4;.which projects into the axle bore. Thus it willbe seen that a wheel hav- .ing a hub portion of relatively small diameter is provided without the enclosing caps which have heretofore been commonly used and encircling the inner end of the wheel hub. The axle 6 having shoulder 8 rotates .in journalboxesQO which are the supporting neans -for the niinecar or other structure indicated at 21, and in assembling the parts the journal boxesQOare secured to the car body after which the axles are threaded through ;such journal boxes and the collars 7 are placed in position in contact with the shoulders 8on the-axles, after which the wheel. assembly with the annular perforatedinember-B, the-roller bearing sleeve '18 and roller bearings 19 are threaded upon the axle, after which the flanged washer 9 is placed upon the reduced outer end portion 6 of the axle and the linch pin 6* is projected through coincident perforations in the washer 9 and the axle at 6 thereby securing the wheels in position upon the axle and securing such pins against end thrust, that is, thrust longitudinally of the axle. So that, in normal service, the collar 7 serves as a stop to prevent the inner face 1 of the wheel hub contacting with the outer face 20 of the journal box, thereby preventing the usual frictional abrasion and wear common with this type ofwheel. Where it is desirable to do so, an additional perforated washer 9 these parts.
